When facility not specified to syslog() method, use default from openlog() (This is how it was claimed to work in the documentation) - Potential resource leak of o_ident, now cleaned up in closelog() - Minor comment accuracy fix.95/06/29 (Steve Clift) - Changed arg parsing to use PyArg_ParseTuple. - Added PyErr_Clear() call(s) where needed. - Fix core dumps if user message contains format specifiers. - Change openlog arg defaults to match normal syslog behavior. - Plug memory leak in openlog(). - Fix setlogmask() to return previous mask value.******************************************************************//* syslog module */#include "Python.h"#include <syslog.h>/* only one instance, only one syslog, so globals should be ok */staticPyObject*S_ident_o=NULL;/* identifier, held by openlog() */staticPyObject*syslog_openlog(PyObject*self,PyObject*args){longlogopt=0;longfacility=LOG_USER;PyObject*new_S_ident_o;if(!PyArg_ParseTuple(args,"S|ll;ident string [, logoption [, facility]]",&new_S_ident_o,&logopt,&facility))returnNULL;/* This is needed because openlog() does NOT make a copy * and syslog() later uses it.. cannot trash it. */Py_XDECREF(S_ident_o);S_ident_o=new_S_ident_o;Py_INCREF(S_ident_o);openlog(PyString_AsString(S_ident_o),logopt,facility);Py_INCREF(Py_None);returnPy_None;}staticPyObject*syslog_syslog(PyObject*self,PyObject*args){char*message;intpriority=LOG_INFO;if(!PyArg_ParseTuple(args,"is;[priority,] message string",&priority,&message)){PyErr_Clear();if(!PyArg_ParseTuple(args,"s;[priority,] message string",&message))returnNULL;}Py_BEGIN_ALLOW_THREADS;syslog(priority,"%s",message);Py_END_ALLOW_THREADS;Py_INCREF(Py_None);returnPy_None;}staticPyObject*syslog_closelog(PyObject*self,PyObject*unused){closelog();Py_XDECREF(S_ident_o);S_ident_o=NULL;Py_INCREF(Py_None);returnPy_None;}staticPyObject*syslog_setlogmask(PyObject*self,PyObject*args){longmaskpri,omaskpri;if(!PyArg_ParseTuple(args,"l;mask for priority",&maskpri))returnNULL;omaskpri=setlogmask(maskpri);returnPyInt_FromLong(omaskpri);}staticPyObject*syslog_log_mask(PyObject*self,PyObject*args){longmask;longpri;if(!PyArg_ParseTuple(args,"l:LOG_MASK",&pri))returnNULL;mask=LOG_MASK(pri);returnPyInt_FromLong(mask);}staticPyObject*syslog_log_upto(PyObject*self,PyObject*args){longmask;longpri;if(!PyArg_ParseTuple(args,"l:LOG_UPTO",&pri))returnNULL;mask=LOG_UPTO(pri);returnPyInt_FromLong(mask);}/* List of functions defined in the module */staticPyMethodDefsyslog_methods[]={{"openlog",syslog_openlog,METH_VARARGS},{"closelog",syslog_closelog,METH_NOARGS},{"syslog",syslog_syslog,METH_VARARGS},{"setlogmask",syslog_setlogmask,METH_VARARGS},{"LOG_MASK",syslog_log_mask,METH_VARARGS},{"LOG_UPTO",syslog_log_upto,METH_VARARGS},{NULL,NULL,0}};/* Initialization function for the module */PyMODINIT_FUNCinitsyslog(void){PyObject*m;/* Create the module and add the functions */m=Py_InitModule("syslog",syslog_methods);if(m==NULL)return;/* Add some symbolic constants to the module *//* Priorities */PyModule_AddIntConstant(m,"LOG_EMERG",LOG_EMERG);PyModule_AddIntConstant(m,"LOG_ALERT",LOG_ALERT);PyModule_AddIntConstant(m,"LOG_CRIT",LOG_CRIT);PyModule_AddIntConstant(m,"LOG_ERR",LOG_ERR);PyModule_AddIntConstant(m,"LOG_WARNING",LOG_WARNING);PyModule_AddIntConstant(m,"LOG_NOTICE",LOG_NOTICE);PyModule_AddIntConstant(m,"LOG_INFO",LOG_INFO);PyModule_AddIntConstant(m,"LOG_DEBUG",LOG_DEBUG);/* openlog() option flags */PyModule_AddIntConstant(m,"LOG_PID",LOG_PID);PyModule_AddIntConstant(m,"LOG_CONS",LOG_CONS);PyModule_AddIntConstant(m,"LOG_NDELAY",LOG_NDELAY);#ifdef LOG_NOWAITPyModule_AddIntConstant(m,"LOG_NOWAIT",LOG_NOWAIT);#endif#ifdef LOG_PERRORPyModule_AddIntConstant(m,"LOG_PERROR",LOG_PERROR);#endif/* Facilities */PyModule_AddIntConstant(m,"LOG_KERN",LOG_KERN);PyModule_AddIntConstant(m,"LOG_USER",LOG_USER);PyModule_AddIntConstant(m,"LOG_MAIL",LOG_MAIL);PyModule_AddIntConstant(m,"LOG_DAEMON",LOG_DAEMON);PyModule_AddIntConstant(m,"LOG_AUTH",LOG_AUTH);PyModule_AddIntConstant(m,"LOG_LPR",LOG_LPR);PyModule_AddIntConstant(m,"LOG_LOCAL0",LOG_LOCAL0);PyModule_AddIntConstant(m,"LOG_LOCAL1",LOG_LOCAL1);PyModule_AddIntConstant(m,"LOG_LOCAL2",LOG_LOCAL2);PyModule_AddIntConstant(m,"LOG_LOCAL3",LOG_LOCAL3);PyModule_AddIntConstant(m,"LOG_LOCAL4",LOG_LOCAL4);PyModule_AddIntConstant(m,"LOG_LOCAL5",LOG_LOCAL5);PyModule_AddIntConstant(m,"LOG_LOCAL6",LOG_LOCAL6);PyModule_AddIntConstant(m,"LOG_LOCAL7",LOG_LOCAL7);#ifndef LOG_SYSLOG#define LOG_SYSLOG LOG_DAEMON#endif#ifndef LOG_NEWS#define LOG_NEWS LOG_MAIL#endif#ifndef LOG_UUCP#define LOG_UUCP LOG_MAIL#endif#ifndef LOG_CRON#define LOG_CRON LOG_DAEMON#endifPyModule_AddIntConstant(m,"LOG_SYSLOG",LOG_SYSLOG);PyModule_AddIntConstant(m,"LOG_CRON",LOG_CRON);PyModule_AddIntConstant(m,"LOG_UUCP",LOG_UUCP);PyModule_AddIntConstant(m,"LOG_NEWS",LOG_NEWS);}
